"Classic makeup and beauty" by Mary Quant - Correcting face shapes
ROUND To reduce Ihe width of a round face, use a darker foundation underneath the cheekbones to give the face more angles. Blend up into the hairline. Dot a lighter shade above the cheekbones to highlight and on the lip of the chin to counteract the moon shape. Apply the base foundation and blend well. Reapply the lighter and darker shades if necessary. Brush blusher along the cheekbones.
HEART To even up a heart-shaped face, use a darker shade of foundation on the sides of the forehead to help reduce the width of the face, and also on the tip of the chin to make it look less pointed. Dot a lighter shade just above the cheekbones to highlight, then apply the base foundation, blending well. Reapply the lighter and darker shades if necessary. Brush blusher along the cheekbones blending it up onto the temples.
